摘要:
One embodiment of the present disclosure includes an electronic device. The electronic device includes an enclosure and a button connected to the enclosure and movable relative thereto. The button includes a button cap defining a user input surface, a first magnetic element operably associated with one of the button cap or the enclosure, and a coil operably associated with the other of the button cap or the enclosure. Movement of the button cap relative to the enclosure, such as due to a user input force, causes the first magnetic element to induce a current in the coil and the induced current is correlated to a user input to the button cap.

A system permits wirelessly controlling the duty cycle of alternating current at a wall electrical outlet (152) remote from a wall electrical outlet (144) which is controlled by a wall switch (142).
摘要:
A synthetic fault signal generator assembly is remotely located on a branch circuit downstream from a circuit breaker protecting a load. The synthetic fault signal generator assembly is configured to detect an improper circuit condition that is not independently detected, detectable, or actionable by the circuit breaker such as, for example, a load or outlet receptacle specific problem that can lead to equipment damage or property damage if not mitigated. In response to the improper circuit condition being detected, the synthetic fault signal generator assembly generates a synthetic fault signal, which causes the circuit breaker to trip. The synthetic fault signal generator assembly can inject the synthetic fault signal into the branch circuit to provide the synthetic fault signal to the circuit breaker.

A switch apparatus is provided. The switch apparatus includes a switch main body, a switch actuator, a housing and at least one pressure compensator. The switch main body includes multiple of contacts. The switch actuator is coupled with the switch main body and configured to trigger movement of the contacts. The housing accommodates the switch main body and the switch actuator and is filled with insulation fluid. The pressure compensator is in fluid communication with the housing and has a variable volume to regulate pressure inside the housing equal to external pressure surrounding the housing. A system having the switch apparatus is also provided.
摘要:
An intelligent electrical switch comprising a conventional mechanical switch connected to a computer system in communication with an external device and receiving instructions therefrom. The switch may be installed in an existing circuit to replace one switch in a multi-way wiring geometry, and includes a sensor detecting current on the neutral line. By determining the circuit state, the switch can determine whether, when instructions are received wirelessly to power the circuit on or off, the mechanical switch element should be toggled.

Provided is a power router to construct a power network system in which power cells are asynchronously interconnected. The power router includes a DC bus, a power conversion leg having a function of bidirectionally converting power, and a controller that controls an operation of the power conversion leg. The power conversion leg operated in a master mode supplements (or sends) an insufficient (or excessive) power from (or to) a connection partner, when a voltage of the DC bus decreases (or increases) from a rated voltage. The power conversion leg operated in a designated power transmission/reception mode sends a designated power to the connection partner or receives the designated power from the connection partner according to a designation from a management server. The controller sets the mode of at least one of the power conversion legs to the master mode during the operation of the power router.
摘要:
A residual current circuit breaker having a core-balance current transformer for detecting a residual current, wherein a secondary winding is arranged on a core of the core-balance element transformer, wherein the residual current circuit breaker has an AC measurement arrangement and a DC measurement arrangement, wherein the AC and DC measurement arrangements are designed to operate simultaneously and in parallel.
